imho, they should both be part of the huge Nokia stanza which is marked
<!-- E51/6300/3109c/6120 Classic/E71/E70/N95-3/E90/N70/E61/N95-2/N96/N82/N82 (alternate chip)/E66/E61i/E60/N93/N71/N77/N90/N91/N80/E62/N76/N73/N92/N72/E50/N75/N93i/E65/N78 -->
The N78 is in there already, but using a different USB id (might be a hardware revision..), and the 6500c is almost identical to the 6300, which is also in that list already.
I guess the attached patch does what I just described here (not tested)
